The bottom closure 4' isfonly capable of small Emotion its moreuientheing'controlled conreniently hy the stops 6'; o'r -if"'desired-' other mechanical,"devices so that as sil eontainer 1 is moved into the charging position shown in Fig. 2 over the opening 3 in the furnace crown 7, the said closure 4 mores l'ly.gravity with it until its stop 6 engages with a stop 8 arranged in such-a position in the furnace crown that the lip of said closure has been'mm'crl into a position in which the material passing from the eon- 'tainer' cannot be diseharged upon the top of the furnace where it would prevent the closin'gof the door 9 adapted to cover the furnaoe cl'iarging opening 3. \Vhenevcr the container l is swung outwardly itahuts the closure 4 and moves saidclosure along with it.' The said door 9 is mounted on one. or more lever arms l0. adapted to turn with said door on the. pivot or pivots ll iuount ed on the furnace (:rmvn 7. Said door is tainer 1 and by the link 13 wit 7 anism for operating the containt I s illustraded in Figs, 1 and 2 thisi m ghanisni may consist of an iill lltlfi't mmcagm the spindle of a chainivheel 15, said arrn 14; he

ing pivotally connected at one endwith the 1 link 13 and carrying at the other end a-countel-weight 16. Tt will he obvious that when the chain wheel 15 is tlll|1((l l) the opera tor through the chain wheel 17 and chain '18, the arm 14- willmove easilywi'th saiid wheel 15 owing to (hecounterweight I6, 'to .tl'ic positionfshoii n in Fig. 2, thereby lifting the door t) on its pivots 'llto a position clear of the furnace charging i'ipening 3' and: at the- .same time moving. through the link 12, the

over said charging opening. *Wheii it is dc sired to return the container 'aft eri the material has been discharged into the furnace the operator will turn the chain wheel 1-5 in the opposite direction and the Wei ht of-the cover 9 and its link mechanism-Wi l balance the weight of the counter weight 16 thereby allowing-the mechanism tobe easily moved back to a position in which the cover 9 is over the opening 3 and the container is in the position shown in .Fig. 1 with its bottom closed bythe Container closure 4.

In Fig. 3 I show, av nodified form of my invention in which a cover- 9- is mounted upon parallel links instead of the arrangement shown in Figsl and 2 in which the cover 9 is pivotally -mounted on the crown of the furnace by one or more lever arms 10. v

What. I claim as my invention is:

-1. .In apparatus for charging dcsti'uctor furiiaces with pre -arranged quantities of material, the combination of a swinging container adap ed to receive the; desired quantity of material i'neans simultaneously movable wit-h said container for uncovering the charging opening of the furnace, aclosure, for the lower end of 'saidcontamer movable with the container through a portion of its movement, and means for overcoming the resistance of said container to swinging as itis loaded.

2. In apparatus for charging destructor furnaces with pre-arra ged quantities of material, the combination of a swinging eontainer adaptedto receive the desired quantities ofmaterial, a furnace provided with a charging opening, a pivoted door adapted to cover said charging opening, and means including said pivoted door for. swinging said container into engagement with said opening and simultaneously moving'said door on itspivot and uncovering-said openmg. V Y

3.- In apparatus for charging destructor furnaces with pre-arrangcd quantities of material, the combination of a swinging container adapted to receive the desired quantities of material, a furnace chamber provided with a charging opening,'.a bottom closure adapted to open saidcontainer during its movement to the charging opening, a pivoted door adapted to cover said charging opening, and meansincluding said pivoted door for swinging said container into engagement with said charging opening and simultaneously moving said door on its pivot and uncovering said opening.

4. In apparatus for charging destructor furnaces with pie-arranged quantities of materiahthe combination-of a. swinging contamer mounted onip votall'y supported arms and adapted to receive the desired quanti ties of material, a-furnace chamber provided with a charging opening, a swinging bottom closure adapted to'swing with'said container, means for arresting the movement of said .bottom closure to open said container during its movement to said charging openmg, a pivoted door adapted to cover said and adapted to receive the desired quanti-- ties of material, a furnace chamber provided with a, charging opening, a swinging hot.- tonrclosurc adapted to swing with said container, stops for arresting the movement of said bottom closure to open said container during its movement to said charging opening,a pivoted door adapted to coversaid charging opening and means including Said pivot-ed door for SWll'lglngfitlld container into engagement with said opening and simultaneously moving said i door on its pivot. and uncovering said gpiaiiing.

said container 6 In apparatusforch rging destructor' furnaces with prc arr I 0 material, the combination of a swinging container adapted to receive the desired quantities of material, a furnace provided with a charging opening, a pivoted door adapted to cover said opening link mechanism connectingisaid swinging container with said door in such a manner that as said container ,is moved to a position in which it is in engagement over the charging opening said door is simultaneously turnedon its pivot-. and removed therefrom while when said" container is moved back to position in which it can be filled thesaid door is carried to its first position over said charging opening, a double armed lever adapted o be turned by the operator, a link con eeting one end of said double armed levcrw th' said charging opening and a counter QGI-glit at the other end of said double armed leilr'.

7. In apparatus for charging destructor furnaces with pro-arranged quantities jof material, the combination of a swinging container, adapted to receive the desired quantities of ma terial, a. furnace chamber provided with a charging opening, a pivoted door adapted to cover said opening, parallel links connecting said door with the furnace crown,
